Rich Sav Posted January 29, 2011 Report Posted January 29, 2011 Basically when i done all the injection setup i went on the rollers and managed 170bhp which was perfect cus classic ford show was the following weekend. While racing at classic ford i wasnt getting the times i was hoping infact i was slower than before and i had more power. So went back on the rollers after the show and for some reason i had lost 30bhp?? I decided a winter rebuild was in order so continued 2 use the now 140bhp for a bit of fun on the road Winter arrived and they started 2grit the roads so i started 2 strip the engine thinkin rings had gone or i had lost a lobe on the cam or my cam timing might of moved. But all seemed ok?? My dad decided 2 ring andy baker from accrilite pistons who made my pistons and he said 2 bring them down 2 him and he'll give them a look over. Just from looking at the pistons he said it had been running lean and due to that the pistons had got hot and when cooling had shrank in diameter 2.5 tho which is why i was loosing the power So ive ordered a set of new pistons and rings. Got my bore be honed and goin 2 do a nice fresh rebuild. I cant wait 2 see what its goin 2 achieve once its set up again
4DOOR-SHERWOOD Posted January 29, 2011 Report Posted January 29, 2011 you have been busy then mate! Hope you get it all sorted out soon!
dave waudby Posted January 29, 2011 Report Posted January 29, 2011 thats strange pistons shrinking, im sure you will build a very good fast engine
Mrs O/H/C Posted January 29, 2011 Report Posted January 29, 2011 Look forward to you racing again this season
w p e Posted January 29, 2011 Report Posted January 29, 2011 if thats the case rich i'd look at another piston supplier. so when it got hot did you gain power then?. 2.25 smaller must have been blowing by big time with lots of crankcase pressure?
turnover Posted January 29, 2011 Report Posted January 29, 2011 rich normally the piston expands and if your bored the block 2.5 though oversize of the manufactured settings it would of been fine for a good thrashing engine ,maybe a bit of piston slap when cold but fine when hot,still im sure you know what your doing and hopefully should pip in the 12s
harris horse power Posted January 29, 2011 Report Posted January 29, 2011 Glad you found the problem should be rapid this year Ive gone the same route for the pinto and bought some throttle bodies
Rich Sav Posted January 30, 2011 Author Report Posted January 30, 2011 if thats the case rich i'd look at another piston supplier. so when it got hot did you gain power then?. 2.25 smaller must have been blowing by big time with lots of crankcase pressure? Was breathing quite heavy and filled the catch tank up easy thats why i thought it was the rings. Dont think it gained power when it was hot but not sure. Going 2 use a different rollers this time and get it re mapped a bit richer so it dosnt happen again. Going 2 use Aldon ive used them b4 and liked the way they worked and they got me 2 my 13.2 previously rich normally the piston expands and if your bored the block 2.5 though oversize of the manufactured settings it would of been fine for a good thrashing engine ,maybe a bit of piston slap when cold but fine when hot,still im sure you know what your doing and hopefully should pip in the 12s the pistons showed they had rocked a bit in the bore which is why ive had a hone 2 freshen it up that must of been while it was cold as u said lookin 4ward 2 rebuild it and see what comes of it anyway if i creep in to the 12's il be well happy in my all steel all glass bufty escort cheers 4 thge responses btw much apreichiated
